In California, there are currently no state licenses, requirements or accreditation for these positions. However, there are a number of patient advocacy certificate programs offered online and through universities across the United States.
Call your hospital and ask if they have a patient advocate on staff. Or you can search online for a patient advocate or patient representative in the hospital where you received care.
Nursing, health-related programs, business, social work, and social science tend to be the preferred degrees by employers looking for patient advocate candidates.
